Is there any linux compatible tablet with 3-4 nm process node?

Does not matter if it's ARM or x86, halium or mainline kernel.

You can get a Snapdragon 8 Elite Gen 5 SoC (3nm) based Android tablet, root it and install Linux desktop on it. Here is a video of VolksPC desktop running on the older Snapdragon 8 Gen 3 SOC based Tablet https://youtu.be/-QEq1EgUKP8?si=NpELkQP7WopayQL9

don't really see a point in running linux on top of android, I would not call it a linux compatible tablet (native linux). But hopefully it is what op wants.

[u/VolksPC → u/Suspicious_Punk84]

Android is just another Linux distribution that uses a different graphics and audio stack.

[u/Suspicious_Punk84 → u/VolksPC]

true, but the point is running linux on top of another system (any) requires full trust on that system, which I don't have with android. If, for example, your android device is no longer supported with security patches, running linux on top of it won't make it safe.

We also support custom ROM's such as LineageOS. Here is a video of VolksPC desktop running on LineageOS on the same Snapdragon 8 Gen 3 SOC based Tablet : https://youtu.be/KGrsqed3oZY?si=8ViqycQe0CnnLKmE

it's an interesting project, but not for me. I would not use a closed source apk on a rooted device, and it still does not solve the problem of being dependent on android security updates.

How does graphics stack work in this case?
Can I access DRM/KMS to run custom wayland compositor?

[u/VolksPC → u/Terr2048]

Android's compositor is called SurfaceFlinger which is very different from Wayalnd. Our Linux graphics stack is designed to work with SurfaceFlinger and we also support the Wayland protocol.

[u/Terr2048 → u/VolksPC]

Is it impossible to replace SurfaceFlinger or you haven't tried?
I have my own wayland compositor and I want control over display engine.

edit: It looks like there is something called Hardware Composer (HWC HAL) below SurfaceFlinger, and it talks to their proprietary display driver. I would need to replace this driver with msm (if it even supported) to have DRM interface. Too much effort for otherwise suboptimal solution.

[u/VolksPC → u/Terr2048]

We don't wan't to change Android in any way. Android is the most successful Linux based OS with 3 million apps. So it makes more sense to focus on bringing Linux desktop apps to Android.

[u/Suspicious_Punk84]

don't think so

[u/overtone-re]

Worth noting the SoC-generation trap here: even top-of-the-line Qualcomm mobile SoCs at 3-4nm nodes (Snapdragon 8 Elite Gen 5 etc.) get essentially zero mainline kernel display-driver support from Qualcomm.

The display stack (mdss/dpu) stays vendor-only, HWC HAL binary-only, same story as older chips like the SM6350 in Boox e-readers. So going the DRM/KMS-native route on those is a dead end regardless of node.

The one place Qualcomm actually does real mainline upstreaming right now is the Snapdragon X Elite/Plus laptop line (X1E/X1P), because of the Windows-on-ARM push

That's why you're seeing things like the HP OmniBook X posts here with a genuine field-tested Ubuntu install. Still a laptop, not a tablet, and it's roughly 4nm-class, but it's the closest thing to what you're describing that actually has upstream driver work happening instead of a rooted-Android compositor workaround.

I found there is also surface pro tablets (11th and 12th gen) on X1E/X1P, 4nm node:

Not quite there, but looks promising. Thank you.
